Because my motherboard has a mini-PCI slot and because the GPU has a long bracket (goes past the motherboard when installed in the system), a double layer of mounts is required.

Step 2: Choose the Materials , Make Measurements and Start Building

The materials you will need are:

- aluminium angle bars 15mm x 15mm (at least 3 meters)

- transparent acrylic glass

The measurements are based around the mini-ITX motherboard that was chosen. The board measures 170 mm x 170 mm. You can see the layout of the components in one of the pictures above. Here are the measurements for the base of the unit that i have chosen to use (yours may deffer depending on your preferences):

You will need to cut 5 pieces of acrylic glass panels (i did not cover the I/O side) with the following sizes (as reference):-290 mm x 193 mm (two)

-193 mm x 155 mm (two)

-290 mm x 155 mm (only one)

After that, start cutting pieces from the aluminum angle bar to surround the bottom panel (290 x 193) to get a aluminium frame. Do this process with the other panel to get two assembled pieces. Secure the corners of the bottom frame with countersunk screws. Next, secure with hot glue the remaining panels to the base and join the cover with the rest of the unit. I attached the cover with screws from the power supply and the side frame on the other side.

Step 3: Done

25/09/2016: so far, the computer does not look pretty and is not fully finished yet, because i don't really have time to finish it (school...), so an update will be coming in the future.

UPDATE 26/07/2018: This computer has served my grandparents for almost two years in this state (behind the TV obviously) until recently, as they switched to a newer computer. Surprisingly, it still works, but I will have to take it apart, because I have no use / any storage place for it. Fare well, old computer!
